Roots supercharger?

Scribe · 05-06-2012, 09:42 PM

I'm very interested in a water-cooled, roots-style blower and it is the only thing I would take over a twin turbo setup. I put it to the forum to photoshop a cowl hood a while back with the idea that it would allow for such a supercharger setup.

Problem is running a belt from what i can see. Having lot of experience with belt wrap and superchargers. This is probably why they don't have one put now.
what I am thinking is a duel charger setup, but noting running a belt will be a pain. I am thinking an electric motor geared for high torque to spin up booth chargers using an rpm signal to run the motor. This keeps parasitic loss off the motor for maximum power.

Attached is a photo of the real "Problem". The solution to which the development company won't tell me until we have an agreement on paper, haha.

Any new updates on this?

It's not really an issue of how much boost, but rather how much peak torque can be made before a piston breaks from overpower, provided no evidence of knock.

My guess is you could make about as much power as with any other kit on a stock motor -- the major difference would be near instant torque and peak boost reached much faster than with other kinds of FI.

Because peak boost can be made more quickly, that will put a little more strain on mechanical parts, but again, my guess is it will overall make similar gains but with better responsiveness.

A roots blown engine just feels like a bigger version of the same engine -- the Z would easily feel like it had a V8 with a roots blower.

Isn't that the point? Haha.. I love boost, don't get me wrong, but I am coming from the subaru world were it is mash the gas- wait for boost- wait for boost- have a drink - wait for boost- ook there it is. Some actual throttle response is very nice.
